Objective: The aim of this study was to compare metacognition and its relationship with aggression among drug addicts, drug-quitting addicts, and non-addicts. Method: In this causal-comparative and correlational study enrolled 62 drug addicts, 51 individuals in addiction-quitting stage, and 96 no- addicts through convenience sampling. Subjects were investigated by the metacognition questionnaire (MCQ-30) and the Ahvaz Aggression Questionnaire.
Results: Multivariate analysis of variance demonstrated significant differences in the mean scores of drug-quitting addicts and non-addicts in negative beliefs subscale related to uncontrollability and risk (F=3.65, P<0.0001), beliefs related to cognitive confidence (F=9.27, P<0.0001), beliefs about the need to control thoughts (F=14.51, P<0.0001), and the total measures of metacognition (F=9/96, P<0.0001). Also, all the components of metacognition across the groups were found to have a significant positive correlation with aggression (P<0.0001 and 0.05, respectively). Multivariate regression analysis results showed that 0.08% variance in behavior of anger and nervousness, 10% variance in behavior of malice and obstinacy, 12% and 13% variance in insulting and offensive behaviors as well as aggressive behaviors would could generally be explained through metacognition.
Conclusion: Our findings suggested that drug addicts tend to have a weaker metacognition as compared to non-addicts. The increase in the intensity of aggression was shown to be related to the increased cognitive dissonance. Such results retain important implications in the prevention and treatment of addiction and aggression.
